Filed: 1974-08-22
Abstract: 1477213 Electronic musical instruments MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 22 Aug 1974 [24 Aug 1973(2)] 36972/74 Heading G5J In an electronic instrument a walking bass accompaniment corresponding to any depressed keys is derived by suitably triggering AND gates 401-16 by an n-bit counter 10 working through a ring counter 6 on modulo 2<SP>n</SP> and corresponding keys 101-116 whereby pulses from a high frequency generator 7 are registered by the binary counter 10 to step the output from ring counter 6 on to successive lines 501-16 until there is correspondence with a closed key when corresponding tone generators 301-16 pass signals through the gates 401-16 and simultaneously the transmission of further high frequency pulses to the binary counter is blocked. In the embodiment shown counting is restarted by pulses from a rhythm generator arranged to reverse the count direction on the first beat of every bar. In this case the binary counter 10 is an up-down counter. Lower octaves of the resulting walking bass may be obtained by insorting a frequency divider 15. In another embodiment (Fig. 5, not shown) the counter 10 operates until there is coincidence at additional AND gates (701-4) from the output of a second ring counter (8) and the rhythm generator. OR and AND gates may be respectively interchanged with NOR and NAND gates.

Abstract: 326,543. Blackstone, G. M., Carter, F., and Carter, E. Dec. 15, 1928. Lever-actuated pumps; stroke, varying.-Apparatus for injecting liquid fuel into the combustion chambers of internal-combusion engines as described in Specification 228,261, is modified in that the injector plunger is adapted to act as a pump, and a non-return valve is provided between the injector plunger and the fuel nozzle. Secured to the combustion chamber a, Fig. 1, is a housing b carrying both the fuel nozzle, which is provided with a spring-loaded valve adapted to be opened by the pressure of the fuel, and the injector plunger c. The plunger c is connected to a stem e provided at its outer end with a stop e<2>, and a sleeve g connected to a head g<1> slides on the stem e. Springs d, f, bearing at one end against a collar on the sleeve g, respectively bear at the other end against the fixed housing and a collar on the stem e. The head g<1> is actuated by a bell-crank lever h operated from the engine cam shaft through a rod h<2>, the outward movement of the head being limited by the engagement of a collar h<3> on the rod h<2> with a governoractuated stop i<2>. in the passage m<1>, Fig. 2, connecting the fuel receiving chamber l of the plunger c with the chamber m of the fuel nozzle, a non-return valve m<2> is fitted. The fuel valve j is loaded by a spring j<2> and also by an auxiliary spring k acting through a rod k<1> and a bell-crank lever k<2>. In operation, the sleeve g is moved outwards by the spring d carrying with it the plunger c, and fuel from the supply conduit l<5> is drawn through the valve l<2> into the chamber l. Just before the injection period the lever h is actuated and the sleeve g is moved inwards, thus compressing the spring f against the abutment of the fuel in the chamber l. At the forward end of its stroke, a lug h<4> on the lever h engages the rod k<1>, thus relieving the fuel valve j from the pressure of the spring k, whereupon the valve j opens and the fuel is forced from the chamber l through the valve m<2> and the fuel nozzle into the combustion chamber.

Abstract: 1,271,648. Variable geometry aircraft wing. OPERATION SIGMA Ltd. 6 Aug., 1969 [6 Aug. 1968], No. 37485/68. Headings B7G and  B7W. A variable geometry wing, particularly for a glider, comprises a fixed forward part 9 and an adjustable aft part 14 which may slide between one position (Fig. 6) in which it is housed within the front part 9 and another position 14<SP>1</SP> (Fig. 8) in which it is extended to increase the chord and camber of the wing. A flexible section 18 of the lower surface of the wing is biased so that at all times it is in contact with the extensible part 14, and the hinged control surface 15 remains exposed in all positions of the part 14. Spanwise movement of parallel control-rods 23 and 27 causes movement of bell-cranks 25 and 26, which in turn move wishbones 21 and 24 which are pivotally attached to the part 9, and these move control-rod 20 in a chordwise direction, thus extending or retracting the part 14. A plurality of such controlling devices is dispersed along the wing; if the wing tapers then the length of the wishbones and the crankarms is progressively reduced from root to tip so that a given displacement of the control-rods 23 and 27 will cause progressively less chordwise movement of the part 14 towards the tip (Fig. 10, not shown). Arrangements are described whereby outer portions of the wing may be detached from a central portion (Fig. 11, not shown), and a readily detachable connection between the central portion and the fuselage is described (Figs. 12 and 13, not shown).

The removable unitary assembly is supported in operational position by members 26. The liquid circulating system comprises a pump rotor 12 and an apertured tube 16, the rotor being driven by magnetic coupling with a motor-driven magnet 19, 20 external to the reservoir. The laser may be directly coupled to an ophthalmoscope for retina treatment, and when hand held may have a moving-ball gravity operated pump instead of the motor-driven rotor 12.
Patent GB-921246-A (GB)
Title: Information storage and search system
IPC: G11B27/32
Filed: 1960-11-07
Abstract: 921,246. Electric digital-data-storage apparatus. GENERAL PRECISION Inc. Nov. 7, 1960 [Dec. 10, 1959], No. 38141/60. Class 106 (1). In a data storage system, data is selected by means of an identifying key or tag portion. As described, data is stored on a magnetic tape in a tape unit 20, Fig. 5, which is utilized in conjunction with a data processor (not shown) to which data is fed from an " or " gate 150 and from which data is received by a circuit 32. Data is stored on sixteen-channel magnetic tape 10, Fig. 3, in the form of data characters, each character being of seven binary bits arranged in parallel, either in channels 1, 3, 5, 9, 11, 13, 15 or in channels 2, 4, 6, 10, 12, 14, 16. Thus two interlaced characters are stored in each " column " of the tape. A word on the tape is constituted by six pulse times, i.e. is comprised of twelve characters (six pairs). Eight words form one data block. Channel 7 of the tape is used for timing pulses and channel 8 stores block addresses, the address in each block being the address of the succeeding block. The first eighteen characters (nine pairs) in the block form the key portion. Input to tape.-To enter data on the tape, the address of the block in which the data is to be entered is stored in a circulatory register 120, the data itself being stored in a magnetic core buffer store 22 which is loaded with the data from the data processor via the input circuit 32. The block addresses read sequentially from the tape are temporarily stored in a circulatory register 54, the contents of the registers 54, 120 being compared in a circuit 56, the attainment of equality causing an output which is applied to a circuit 30 to cause the data from the buffer store 22 to be written on the tape under control of timing signals derived from the tape. Output from tape.-To extract data from the tape, the " key " of the desired block is entered in the circulatory register 120. The keys of blocks scanned on the tape unit 20 are entered sequentially into a magnetic core buffer store 44 whence they are transferred to a register 86 (Fig. 13, not shown), and compared with the desired key in a comparison circuit 90 (Fig. 14, not shown). When equality is obtained the circuit 90 produces an output to cause (1) the selected data to be read from the tape to a buffer core store 45 (Fig. 17, not shown), (2) the address of the selected block to be read into a core register 126, (3) the key portion of the selected block to be transferred to a core register 126 (Fig. 6, not shown). When the data processor requires the selected data, it applies a signal to unload, sequentially, the block address from the register 126, the key from the register 126 and the data from the buffer store 45, these items being read out through the " or " gate 150. The register 120 is constructed to contain a plurality of keys and means are described (Fig. 21, not shown) in which two alternately used output buffer stores 45 are employed to enable a second search to be effected when a first search has located its desired data.
Patent GB-801582-A (GB)
Title: Process for the production of alkoxyglycerolesters from lipid mixtures
IPC: C11B1/02
Filed: 1956-12-13
Abstract: Alkoxyglycerolesters are obtained by treating an alkoxyglycerolester-containing natural raw material in the form of fats, mixtures of fats, or oils with lipolytic enzymes capable of bringing about selective hydrolysis of the triglyceride content as opposed to the alkoxyglycerolester content and thereafter separating the free fatty acids and glycerol thus liberated from the alkoxyglycerolesters.  A suitable specific enzyme can be obtained from, for example, the seeds of the plant Ricinus communis. Separation of the esters from the hydrolysed products can be effected in manner known per se.  In examples, alkoxyglycerolesters are isolated from the liver oils of the fishes Somniosus microcephalus and Squalus accanthias, bone grease and egg oil by specific hydrolysis with pulverized and ether extracted seeds of Ricinus communis or lipase obtained therefrom in acetate buffer at pH 4.5 usually in the presence of petroleum ether.  In one case, manganese sulphate is added.  Working up methods used include ethereal extraction of the alkalinized reaction products, alkaline extraction of the oily layer, and steam distillation.
